Provenance — the recipe fingerprint, a within-base instrument
◐ WITHIN-BASEOn finetunes that are statistically identical by surface statistics, the fingerprint distinguishes the producing recipe near-perfectly within a fixed base. The honest scope: this is a within-base read — recipe identity is calibrated per base family and does not carry across base families. Each model card states which base a fingerprint is calibrated against.
Recipe identity — within-base, against the aggregate-statistics baseline
Within-base only, per base family, never cross-family. Tone ◐ inferred, not ● proven-broad.
